Just added a button to allow you to rate posts that will show up at the top of the post. It’s a standard 0-5 stars things, like on amazon. Also, you can now give a thumbs-up or thumbs-down to comments you do or do not like. You shouldn’t have to sign-in to do either of these things, either. Enjoy!
4/17 Update. Playing with the page layout a bit, please forgive the dust.
